' 3 Claims.

This invention relates to locomotive seats.

At the present time, as far as American railroads are concerned, the requirement is that 10- comotive seats be securely fastened to the floor of the locomotive cab at all times. Locomotive seats as now used and constructed are made of wood and are fastened to the floor of the cab in one position, without thought to the convenience of the engineer.

An object of the present invention is to provide a locomotive. seat that maybe adjusted to different positions and to different heights to suit the convenience of the individual engineer operating the locomotive, and which seat, at the same time, may be securely fastened to the floor of the cab to meet. present railroad requirements. I

The invention, together with its objects and advantages will be best understood from a study of the following description, taken in connection with the accompanying drawings, wherein:

Figure l is a top plan view of the seat with the upper section of the seat removed.

Figure 2 is a perspective view of the upper section of the seat.

Figure 3 is a vertical sectional view taken substantially on the line 3-3 of Figure 2, but with the upper section of the seat in an elevated position.

Figure 4 is a perspective view of a floor plate.

In accordance with the present invention there is provided a dead or stationary floor plate 5 provided with openings 6 to accommodate screws or other fastening elements I, through the medium of which the plate 5 is secured to the floor 8 of the locomotive cab.

Resting on the floor plate 5 is the bottom 9 of the lower box-like section I of the seat. This section ID in addition to the bottom 9 has side and end walls rising vertically from the "bottom 9, and the section III is preferably formed wholly of metal.

Further, the seat comprises an upper section II which is of substantially rectangular framelike form, constructed from sheet metal, and adapted to be lowered and telescoped into the lower section II] of the seat.

To support the section II in either raised or lowered position with respect to the section I 0, the latter is provided on opposed walls thereof with internal lugs I2 while the seat section II in eachof twoopposite sides thereof is provided with short notches I3, and in each of twoother opposed sides thereof with longer notches I4.

As shown in Figure 3, to support the section II in elevated position relative to the section I 0, lugs I2 are engaged in the shorter notches I3.

To support the section I I in lowered and telescoped position relative to the section Ill, lugs I2 are engaged in the longer notches I4, as is obvious The section II of theseat supports the upholstered seat Iproper, and the same is hinged adjacent one edge thereof to one side of the section II through the medium of hinges I6 arranged within the confines of the section II and wholly concealed when the seat I5 is at rest on the upper edges of the section II.

Except for the side thereof in which the seat I5 is hinged,the remaining sides of the section" II at the upper edges thereof are bent outwardwardly to provide narrow flanges I'I upon which the seat I5, proper, rests when in the position shown in Figure 3.

Further, in accordance with the present invention, the floor plate 5 has rising therefrom I and adjacent one corner thereof an integral stud bolt I8. To accommodate the bolt I8, the bot-- tom 9 of the seat section II] is provided with a slot arrangement shown in Figure 2 and which consists of a-pair of right angularly related interconnected slots I9, 20, and a diagonal slot 2I that joins the slots I9, 20, at the angle between the slots I9, 20, as clearly shown in Figure 2.

To secure the seat at the desired position of adjustment relative to the floor plate 5, there is threadedly engaged with the stud bolt I8, 9. hand nut 22 adapted to be threaded home against a washer 23 disposed on the stud bolt I8 between the bottom 9 of the seat section I 0 and the nut 22.

Obviously, provision of the intercommunicating slots I9 to 2| inclusive permits of a wide range of adjustment for the seat, permitting the latter to be moved laterally toward or away from the side of the locomotive cab or either backward or forward to suit the convenience of the engineer.

Manifestly, to' adjust the seat to the position desired, the lever nut 22 is loosened and the seat is then slid in the desired direction, being guided to the position desired by means of the cooperating bolt I8 and slot section in the bottom plate of the seat structure. When the desired position is effected, the seat is securely fastened to the cab by tightening the lever nut 22.

The height of the seat may be readily raised or lowered simply by lifting out the section II, giving it a quarter turn, and then placing it in the section III of the seat.

ferred embodiment thereof, made of steel, and

which is adjustable to any desired position to suit the convenience of the engineer operating the locomotive. Also, a seat embodying the features of the present invention will meet the requirements of the railroad, provision being made, as above noted, to securely fasten the seat to the floor of the cab, as is necessary to meet the present railroad requirements.

It is thought that a clear understanding of the construction, utility, and advantages of a seat of this character will be had without a more detailed description.

Having thus described the invention, what is claimed as new is:

1. In a locomotive cab seat, and in combination, a stationary floor plate having a bolt rising vertically therefrom, a lower supporting section having a bottom and vertical walls rising from said bottom, said bottom being provided with a plurality of angularly related intercommunicating slots to accommodate said bolt'and to permit a shifting of the seat supporting section in substantially any and all directions relative to said floor plate, said seat supporting section having pairs of lugs on the inner side of two opposed walls thereof, a second seat supporting section telescoping within the first seat supporting sec- -,tion' and provided on each of two sides thereof with elongated slots to engage said lugs, for supraised position relative to the first section.

2. In a locomotive cab seat, and in combination, a stationary floor plate having a bolt rising vertically therefrom, a lower supporting section having a bottom and vertical wallsv rising from said bottom, said bottom being provided with a plurality of angularly related intercommunicating slots to accommodate said bolt and to permit a shifting of the seat supporting section in substantially any and all directions relative to said floor plate, said seat supporting section having pairs of lugs on the inner side of two opposed walls thereof, a second seat supporting section telescoping within the first seat supporting section and provided on each of two sides thereof with elongated slots to engage said lugs, for supporting the second section in telescoped position within the first section, said second seat section having relatively shorter slots in each of two other opposed sides thereof for accommodating said lugs'for supporting the second section in a raised position relative to the first sectiomand a seat member hinged adjacent one edge thereof to one side of the second seat supporting section and resting on the top of said second section,

3. In a seat of the character described, a pair of telescoping hollow seat-supporting sections, the outer one of said sections having opposed sides provided with lugs on the inner faces thereof, and the inner one of said sections having two opposed sides thereof provided with elongated slots to engage said lugs for supporting said inner section at one position of adjustment relative 'to the outer section, and said inner section also having in two other opposed sides thereof relatively short slots for engagement with said lugs to support said inner section at a second position of adjustment relative to said outer section.
